Sedimentological study of the deposits at the locality “Pod Královým stolcem” (National Park Podyjí/ Thayatal) provides data about the evolution of the deposits within the confined Dyje valley. Deposits of the three facies associations/depositional environment have been recognised in the artificial trench. The first one is represented by alluvial and colluvial deposits formed by gravity flows (debrisflows) and poorly confined waterflows. The prominent facies association is composed of deposits of fluvial channel. Inchannel bedforms (2D and 3D gravelly and sandy dunes) represent their dominant part. Braided fluvial style is supposed and occurrence of aggradational architectural element is interpreted. Soil sediments form the final facies association. Provenance analysis of the fluvial deposits recognised primary source from both local (granitoids of Thaya Batholit), and more distant areas (Moravian and Moldanubian Superunits). Moreover, an intense reworking and redeposition of material from older deposits (as secondary source) is evident. Multiple repeated periods of erosion, bypass and deposition influenced the texture and composition of the studied deposits and represent a characteristic feature of the deposition within deeply confined Dyje valley.
